Coppell TV Repair offers you the essential components needed to repair the most common failure in LG ZSUS board 6871QZH056B 6870QZH004B as shown on the picture below.
Those are the large IC voltage regulator (called IPM) and a fast acting 4A fuse which usually (not always!) burns when the IPM fails.
(You are not getting the board on the large picture; it is put there just for an illustration of what this kit is intended for!)
Please read the following carefully and do not hesitate to ask if you have questions:
Easily 99% of the time when the ZSUS board does not work you will need this kit. 80% of the time this kit is all that you will need. Statistics come from our own experience servicing boards, i.e. using this very kit.
A blown 4A fuse on the board (see picture) is a clear indication you need this kit however the lack of blown fuse does not rule it out. Sometimes the power board acts faster than the OEM fuses and shuts off before the fuse blows.
Applying the kit requires advanced soldering skills and appropriate equipment. A 50W soldering iron for $15 is more likely to damage the board than help do the job!
We offer board repair service
, but we will reject or at best not give warranty on boards that have been previously worked on. Think twice if you want to DIY or send the board for repair!
If you need other components for your service do not hesitate to contact us - if anyone has them we do!
The kit contains the same components that our own service technicians use.
The IPM hybrid IC in the kit may be different from the one on your board (e.g. Sanyo versus LG), but is guaranteed to substitute it all right. We just buy the ones that work best for us considering both price and quality.
